#220 of 2018 Weird Squealing/Whining upon acceleration
Jun 17, 2002 (6:58 pm)
I am a young and impressionable new 2001 S-10 2.2L automatic owner. I have owned 2 other Chevy products (albeit used), that I thought were wonderful and easy to fix. I am still in the honeymoon with the S-10, so I am hopeful. I have 6500 miles and no prob until I start to here this funny whining noise when I accelerate from 1-2 or 2-3. For the first time I also heard it when I put the truck in cruise control and the engine had to work hard to maintain 65 mph the whining begins and goes away after the engine has plateaued rpms. I took the truck to the dealership and the tech tells me it is a vibration problem from the engine (not the transmission?!?!??). He says GM has no bulletin
and I must be the first with this problem (2 year old truck, I'm the first). The truck is under warranty for 2.5 more years. He says they will "check" with the engineers in Detroit, go figure.
I don't push the truck hard so I assume this must be a factory defect. It has had regular oil changes (3K) and tires rotated etc.. Anyone have any advice?
Thanks for any help

tdcummins: You didn't say if your truck was an extended cab, or where the noise was coming from. If it is an extended cab, have the dealership check the drive shaft. The extended trucks use a split (two section) drive shaft because of the truck's extra length. I've heard of some drive shafts coming out of the factory out of balance. If the whine sounds like it is under your feet, consider a transmission problem. If it sounds like it is coming from the engine, I would look at the water pump, power steering pump, serpentine belt tensioner or alternator. ANY whine in a machine is not good--it suggests there is metal-to-metal contact somewhere. That is always bad because it will lead to premature failure of one or several parts.
ricsch: Sorry to hear GM is not giving you any help on your '97 Blazer's bad engine. GM seems to be trying to pinch pennys, but they end up making enemies. Any good marketer will tell you that a satisfied customer will talk to a few people, but a ticked off customer talks to EVERYBODY! This forum proves that. The few thousand dollars GM saved on a new engine cost them at least one future customer (you) and potentially many more. You may want to talk to a lawyer, letting him know what was said. The communications between GM and your dealer may have implied that GM was going to cover some or all of the costs. If so, a trip to the courthouse will cost them a lot more than the price of a new engine.
meysterman: My 2000 S-10 extended cab has the same problem with the seat. I will be taking it back to the dealer I use to get them to fix it, among other things. I'll let you know what he does to fix it. Keep after your dealer to fix it. The seat not locking in place is a violation of Federal vehicle safety standards and a huge safety risk. If someone were in the seat during an accident, the seat coming unlocked could prove to be fatal. If Chevy doesn't get mine right, I will be talking to the NHTSA about the defect.
By the way, the dealer I use for service is NOT the one I bought the truck from. The selling dealer's service department thinks customer service means you argue with the customer to convince him his truck ISN'T broken, rather than fixing the problem. Since they were the problem, and there are a gazillion Chevy dealers here in San Antonio, I fixed the problem by finding a dealership that listens to customers.
Good luck to all! The S-10 is a great truck, but like any vehicle, they do have a few quirks.

I have a 1996 S-10 with A/C that is not cooling properly. I have checked the freon level with a gauge and it is properly charged. The compressor is also engaging. It seems to blow cool at times and other times not. Has anyone had this problem and what was the solution. I have been told it could be the expansion valve. Thanks for any comments.

Has no txv,i would say you low on 134a.What are your low & high pressures & outside air temp & at what rpm did you check the pressures at.
#224 of 2018 A/C problems...
Jun 25, 2002 (11:38 am)
Keep in mind that 134a pressures are much higher than the old R-12 readings. If you are using an R-12 table or chart for the readings, the pressure could be low for 134a readings. Also, check the fan clutch for failure. A bad clutch won't keep enough air flowing through the condensor on hot days at low speeds. IF you have a proper charge of freon (should be 134a on a '96) and the compressor is engaging, then you may have one of two problems:
1) The heater blend door in the air box in the cab is not opening and closing properly. Let the glove box door hang down (there should be a release to let it come all the way down in the upper left corner of the glove box) and move the A/C control from max A/C to the regular A/C position. If you can't see the door moving, it is stuck, or the vacuum line came off.
2) The valve that controls hot water going into the heater coil may be broken, allowing hot water to flow through the heater year 'round. If so, your A/C is working, it just can't compete with high outside temps AND a heater on full blast.
#225 of 2018 Rear Differential Change?
Jul 03, 2002 (11:02 am)
The owner's manual for my 2WD '97 recommends CHECKING the differential fluid level at certain intervals. I'm at 41K miles. My dealer told me today that I should have already changed the fluid. I've taken several non-GM vehicles over 100K miles without changing diff fluid. Any recommendations?

Jul 04, 2002 (9:20 am)
As far as I know there is no GM recommended fluid change,I looked in the owners & Service Manual.If I planned to keep it I would change it at 100K.I have a 2 wd 99 Sonoma.
#227 of 2018 Cajun: just responded in your other forum...

Do it yourself with synthetic fluid and save a LOT of money over what the dealer would charge.
#228 of 2018 Service Engine light
Jul 13, 2002 (1:53 pm)
my '99 Sonoma (couldn't find a sonoma board, so here I am) has the service engine light coming on ONLY when I travel in hilly country. It's a 2.2L Automatic and has 51,000 on it. Usually after I get back on level ground it will go out. First time it happened, I had just bought some gas, so figured it was a fuel related problem. Had the code checked one time and said the trans was slipping. Why would driving up a hill without a load cause this?
Between this, no performance and my 21MPG hiway, I am ready for a car.
#229 of 2018 Code 1870 slipping TCC
Jul 14, 2002 (9:38 am)
If the transmission has not been overheated a trans shop can repair it fairly easily with a spring kit,the valve body will have to come down.
I keep up on this stuff I have a 99 Son 2.2 auto & air with 32K.I get between 25 & 29 mpg highway,the difference is how fast.
